Spider Lily or Hurricane Lily

Lycoris radiata, known as the red spider lily, hell flower, red magic lily, or equinox flower, is a plant in the amaryllis family, Amaryllidaceae, subfamily Amaryllidoideae. Originally from China, Korea, and Nepal, it was introduced into Japan and from there to the United States and elsewhere. It flowers in the late summer or autumn, often in response to heavy rainfall. The common name hurricane lily refers to this characteristic, as do other common names, such as resurrection lily; these may be used for the genus as a whole.
